Letters Patent No. 94,437, dated August 31, 1869.

INIPROVEIWENT IN MACHINE IOR I BURRING- AND CLEANING- WOOL.

The Schedule referred to in than Letters Patent and making part of the lune.

1'0 all persons to whom these presents may come:

Be it known that I, ZIBA PARKI-IURST, of Milford, in the county of Worcester, and State of Massachusetts, have made a new and useful invention, having reference to Machinery for Burriug, Cleaning, and Garding Wool; and I dohereby declare the same to be fully described in the following specificatiomand represented in the accompanying drawings, of which- Figure 1 is a top view,

Figure 2, a side elevation,

Figure 3, arear-end view, and

Figure 3, a longitudinal section of the machine containing my invention.

In such drawings- A denotes the frame of the machine, it being provided at its rear end with a receiving-mouth, a, a pair of feed-rollers, b b, and a burr-box, c, the said burrbox being disposed, with respect to the first or receiving-card cylinder B, in manner as represented.

Within the burr-box, and at its front part, I arrange what I term a rotary transferrer, G, which consists ofa horizontal shaft, (1, provided with a series of blades or wings, e e e, extended from it radially, every other one of them being serrated on its outer edge.

A top view of this transferrer is shown in Figure 5, it being put in revolution by an endless belt going around its shaft, or a pulley fixed thereon.

The transferrer, while in operation, serves to intercept the loose fibres which may be passing over the top of the upper teed-roller, and to transfer them to the receiving-cylinder.

It also answers to stir up and open theawool on the receivingcylinder, during the transit of. such wool from the feed-rollers to a rotary beater, D, which is arranged directly over the card-cylinder, and on a horizontal shaft, f.

This beater consists of a series of rectangular wings, radiating from the said shaft.

The heater is to be put in revolution by any proper; means, its purpose being to remove from the wool, on the cylinderB, such of the burrs or other extraneous matters as may project beyond the teeth of the cylinder and be carried aronmlwithin the path of revolution of the said heater.

In advance of the receiring-cylinder B, is another such card-cylinder, F, which 1 term a tumbler.

Arranged between the said two cylinders, in manner as represented, is a series of ribs, h It, which are disposed parallel to each other, and obliquely, on a stationary cross-bar, G, in manner as shown in top view inFigure 6.

The purpose of these ribs is to stop the waste wool that may fall from the bite of or between the two cylinders B and E, so that such wool may be caught up by the advanced one.

They also operate to remove the dirt and extraneous matters from the wool beaten against them by the cylinders.

The slanting position of eaco of the ribs causes it to operate to good advantage for the purposes as mentioned, and to clear itselfaf the dirt.

In advance of the cylinder or tumbler F is the main card-cylinder H, and there is arranged between the two, in manner as represented, a stripper or other card-cylinder, 1, whose purpose is to catch the waste ,parts of the said machine is indicated on it by an ribs, arranged directly under the transfcrrer O, or between such and the upper feed-roller.

The revolving parts of the machine are to be provided with suitable-mechanism for putting them in revolution, as may be required.

The wool, in going through the machine, will be bulred, cleaned, and doii'ed, it being understood that it is to be removed from the clofl'er by a comb, such as is in use in ordinary carding-engines.

In such machine I make no claim to the combination of the feed-rollers b 11 and the card-cylinders B, I I, H, and K, such being used in machines of like character and purpose.

What I do claim as of my invention is as follows,

viz

1. The arrangement of the rotary transferrer G with the burr-box c, the teed-rollers b b, and thereceivingcylinder B.

2. The arrangement of the beater D, the receivingcylinder B, the feed-rollers 7) -11, the burr-box c, and the transferrer C.

3. The combination and arrangement of a series of oblique ribs, (as shown at h or 1:, and as above described,) with the receiving-cylinder B and the tumbler F, or with the card-cylinder H and dofler K, the whole being substantially as and'to operate as specified.

4. The combination and arrangement, as described, of either or both the rotary drums L M, with the cardcylinders F I H, and the two series of oblique ribs, the feed-rollers, burr-box c, and receiving-card cylinder B, substantially as specified.
